Move structures used for static allocation of tasks and queues into FreeRTOS.h from their individual API header files.
Add SAME70 Xplained Atmel Studio project.
Update SAMV71 Atmel Studio project to use Studio 7.
Revert some changes to GenQTest.c standard demo task which only function correctly when a queue registry was used.
Minor change to xQueueGenericReceive() to catch the extreme case of data being placed into a queue between a task timing out and leaving the xQueueGenericReceive() function.
Added xSemaphoreGetCount() macro.
Demo app changes:
Updated countsem.c to test the new xSemaphoreGetCount() macro.
+ Add the pre-existing 64-bit Cortex-A53 port layer into the head revision of the main repository.
Demo application updates:
+ Update Zynq demo to use SDK version 2015.4
+ Add task static allocation standard demo to Zynq demo.
+ Make the XScuGic object accessible outside of the vConfigureTickInterrupt(), again in the Zynq demo.
+ Introduced xTaskCreateStatic() to allow tasks to be created without any dynamic memory allocation.
+ When a task notification is used to unblock a task from an ISR, but the xHigherPriorityTaskWoken parameter is not used, then pend a context switch to occur during the next tick interrupt.
Demo application changes:
+ Updated TaskNotify.c to test the case where a task is unblocked by an ISR, but does not use its xHigherPriorityTaskWoken parameter.
+ Updated the Win32 MSVC project to test statically allocated tasks being created and deleted.
+ Introduced StaticAllocation.c standard demo task.
+ Previously, if a task was deleted, the memory allocated to the task by the RTOS was freed in the Idle task. Now if a task deletes another task the memory is freed immediately. The idle task is however still responsible for freeing the memory when a task deletes itself.
+ Added pcQueueGetQueueName() function to return the name of a queue from its handle, assuming the queue is registers.
Demo application:
+ Update GenQTest to exercise the new pcQueueGetQueueName() function.
+ Delete workspaces from old Eclipse examples, leaving just the projects.
+ Rework comments in the MSVC simply blinky demo.
+ Updated all ARM Cortex-M0 ports to include an additional ISB instruction as the scheduler is started.
Demo app files:
+ Fixex build issues in XMC1000 demos.
+ heap_1.c and heap_2.c now support configAPPLICATION_ALLOCATED_HEAP (heap_4.c already did) which allows the heap to be placed by the user rather than the linker.
Demo app changes:
+ SAMD20 project has been updated to use Atmel Studio 7.
+ Support tickless idle when configUSE_PREEMPTION is 0 (previously tickless idle was only supported when the pre-emptive scheduler was being used).
+ If a stack was statically allocated, then don't try freeing it if the TCB cannot be allocated.
+ Remove use of INCLUDE_xEventGroupsSetBitsFromISR() pre-processor macro, as it was not tested anyway.
Demo app changes:
+ Updated SAM4L Atmel Studio project to use Atmel Studio 7.
Kernel source changes:
- Added xTaskNotifyStateClear() API function.
- Added the GCC Cortex-R port (existed for a while) into the main download.
- Improved the IAR RL78 port's handling of different memory model combinations.
- Removed some compiler warnings in heap_5.c.
Demo app changes:
- Added example use of xTaskNotifyStateClear() to the TaskNotify standard demo tasks.
Bug fix - issue introduced in V8.2.2 when the current timer list is empty and the overflow timer list is not empty.
Add PIC32MZ EF (floating point) support and update the MZ demo project to test the flop context switching.
Improve efficiency of the stack overflow checking.
Add CLI to RX71M demo.
General tidy up of new RZ and RX projects - including ensuring the UART driver copes with 0 length strings.
Add stack overflow checking to the [old] PIC24 demo.
- Complete the demo projects for the RX113 using IAR, GCC and Renesas compilers by including a basic UART CLI.
Standard demo tasks:
- Add some volatile qualifiers to variables in IntQueue.c.
Add additional asserts into timers.c.
Trivial changes and changes in demo applications:
RX113 IAR project is not building and running.
Make FreeRTOS_SetupInterrupt() and FreeRTOS_ClearInterrupt() weak symbols in the Zynq SDK repository.
Correct typo in the port layer comments that was cut and paste into multiple files.
+ Added Renesas RXv2 port for IAR.
Demo apps:
+ Demo/Rename the CORTEX_R4F_T_GCC_IAR_ARM directory to just Rename the CORTEX_R4F_T_GCC_IAR.
+ Add IAR project for the RX113.
+ Add RX231 e2studio projects for the RX231.
- Remove configASSERT() if a queue cannot be created, malloc failed hook will be called anyway.
Demo apps:
- RZ/T blinky demo working, but still lots to do to improve the port.
FreeRTOS+Trace:
- Add trace macros for task notifications.
- Update to the latest trace recorder library.
Demo projects:
- Only include the CLI command to show run time states if configGENERATE_RUN_TIME_STATS is set to 1.
- Back out changes that allow mutexes to be given from a semaphore after tests showed issues that would not be fast to fix.
Demo projects:
- Update the Microblaze Kintex 7 project and BSP to use version 2015.2 of the Xilinx SDK.
Zynq ZC702 demo application:
Update the memcpy, memset and memcmp implementations so they don't err with -O3 optimisation.
Update to use the 2015.2 version of the SDK.
Kernel changes:
- Remove an assert that was preventing xQueueSendFromISR() being used to give a mutex from an ISR (mutexes cannot be given using xSemaphoreGiveFromISR()).
- Introduce xTaskNotifyAndQueryFromISR() as the interrupt safe version of xTaskNotifyAndQuery().
Common demo task changes:
- Update IntSemTest.c to prove the theory that it is safe to give a mutex type semaphore from an interrupt using xQueueSendFromISR() instead of xSemaphoreGiveFromISR().
- Update TaskNotify.c to test the new xTaskNotifyAndQuery() from ISR fuction.
